The pattern of warming that we have observed, in which warming has occurred in the lower portions of the atmosphere (the troposphere) and cooling has occurred at higher levels (the stratosphere), is consistent with how greenhouse gases work — and inconsistent with other factors that can affect the global temperature over many decades, like changes in the sun's energy.
